100Ah rated capacity, 1,280Wh rated energy and a 100A maximum continuous-discharge rating support a planned 12V auxiliary system, not engine starting. Use the runtime guide in the gallery as an estimate, then size the inverter, fusing and wiring around your actual loads.
The 339 × 185 × 218mm case sets the starting point for an RV auxiliary system. Confirm tray size, hold-down clearance, terminal access and cable routing before ordering; the Group 31 name does not guarantee a universal drop-in fit.
Use compatible Bluetooth 5.0 monitoring to review state of charge, voltage, current and battery temperature before changing loads or charging sources. Follow the product manual and app instructions for the available functions.
At a listed 9.6kg / 21.16lb, the G31 is easier to move into service position than many comparably sized lead-acid batteries. Use the integrated carry strap for handling, then secure the case with a correctly sized tray and hold-down.
The built-in BMS covers the listed current, voltage, temperature and short-circuit protections. IP65 means dust-tight and protected against water jets, not immersion; secure the battery upright and use correctly sized fuses, cables and terminal covers.
Charging stops below 0°C battery temperature and resumes above 5°C. The listed operating ranges are 0–55°C for charging and -20–60°C for discharging; use the battery within the manual's environmental limits.
Plan LiFePO4-compatible CC/CV charge sources: an AC charger, solar with an MPPT controller, an alternator through a DC-to-DC charger, or a generator feeding a compatible charger. Do not connect sources directly to the battery terminals.
Use matched batteries of the same model, capacity and state of charge. The listed architecture supports up to 4 in series or 4 in parallel, and up to 16 matched batteries in a 4P4S bank; follow the manual for balancing, protection and cabling.
Installation, charging, Bluetooth monitoring and battery care.
Group 31 manual · EN / FR / DE (PDF) ↗The approved G31 reference tiers are 4,000+ cycles at 100% depth of discharge, 6,000 cycles at 80% DoD and 15,000 cycles at 60% DoD. Actual cycle life varies with charge and discharge rate, temperature, maintenance, depth of discharge and operating conditions.
No. Up to 10-Year Life is a product-life reference under suitable use. The 5-Year Limited Warranty covers eligible defects under the model-specific warranty terms; it does not guarantee ten years of product life.
You can contact SuntNeew support for product setup, charging, Bluetooth, installation and after-sales questions. Provide the order information, model number and photos or readings relevant to the issue.
No. This is a deep-cycle auxiliary battery and is not intended to start a vehicle, boat engine or other device. Do not use it as a starting battery.
Confirm the 339 × 185 × 218mm enclosure, terminal position, hold-down, upright mounting, cable route and service clearance. Size conductors, fuses, disconnects, inverter and charging sources for the complete DC system.
No. They are theoretical estimates based on 1,280Wh rated energy and the stated appliance loads. Actual runtime changes with duty cycle, inverter efficiency, battery condition, temperature and the real power draw of the connected equipment.
No. IP65 means the enclosure is dust-tight and protected against water jets. It is not an immersion rating; keep the battery secured, upright and protected in accordance with the product manual.

GROUP 31 FEATURES
Start with verified fit, then follow the G31 story from lighter installation to daily 12V power, Bluetooth visibility, protected charging and a matched expandable system.
1. SETTLE IN
100Ah rated capacity, 1,280Wh rated energy and a 100A maximum continuous-discharge rating support a planned 12V auxiliary system, not engine starting. Use the runtime guide in the gallery as an estimate, then size the inverter, fusing and wiring around your actual loads.
2. FIT THE GROUP 31 BAY
The 339 × 185 × 218mm case sets the starting point for an RV auxiliary system. Confirm tray size, hold-down clearance, terminal access and cable routing before ordering; the Group 31 name does not guarantee a universal drop-in fit.
3. CHECK IT BEFORE YOU OPEN THE BAY
Use compatible Bluetooth 5.0 monitoring to review state of charge, voltage, current and battery temperature before changing loads or charging sources. Follow the product manual and app instructions for the available functions.
4. LIGHTER WORK AROUND THE BAY
At a listed 9.6kg / 21.16lb, the G31 is easier to move into service position than many comparably sized lead-acid batteries. Use the integrated carry strap for handling, then secure the case with a correctly sized tray and hold-down.
5. PROTECT THE BATTERY AND THE INSTALL
The built-in BMS covers the listed current, voltage, temperature and short-circuit protections. IP65 means dust-tight and protected against water jets, not immersion; secure the battery upright and use correctly sized fuses, cables and terminal covers.
6. PAUSE CHARGING WHEN THE CELL IS TOO COLD
Charging stops below 0°C battery temperature and resumes above 5°C. The listed operating ranges are 0–55°C for charging and -20–60°C for discharging; use the battery within the manual's environmental limits.
7. BUILD COMPATIBLE CHARGING PATHS
Plan LiFePO4-compatible CC/CV charge sources: an AC charger, solar with an MPPT controller, an alternator through a DC-to-DC charger, or a generator feeding a compatible charger. Do not connect sources directly to the battery terminals.
8. SCALE A MATCHED BATTERY BANK
Use matched batteries of the same model, capacity and state of charge. The listed architecture supports up to 4 in series or 4 in parallel, and up to 16 matched batteries in a 4P4S bank; follow the manual for balancing, protection and cabling.
